摘　　要：通风系统能否正常运行对矿山的安全生产有着重要影响,对通风系统进行可靠度评价十分必要。以某矿山通风系统为研究对象,基于网络流理论,综合主要影响因子的权值,应用可靠性工程理论计算出各分支风路的可靠性指标值,采用相匹配的算法建立可靠性评价研究模型。运用Matlab软件,结合联络矩阵法的解算思路,通过代码运算,实现联络矩阵法多节点矩阵解算,解得通风网络的可靠度为0.817,表明通风系统较可靠,证明联络矩阵法用于矿井通风网络可靠性评价是可行的。The normal operation of the ventilation network system has an important influence on the safety in mine production,so it is necessary to evaluate the reliability of the ventilation system.In this paper,taking the ventilation system of a mine as the research object,based on the network flow theory and integrating the weight of main influence factors, the reliability index values of each branch air path are calculated by using the reliability engineering theory,and the corresponding algorithm is adopted to establish the reliability evaluation research model.By using Matlab software and combining the solution idea of the contact matrix method,the multi-node matrix solution of the contact matrix method is realized through code operation.The reliability of the ventilation network is 0.817,indicating that the ventilation system is reliable.The conclusion verifies the feasibility of using the method of contact matrix to evaluate the reliability of mine ventilation network.
